This is a serious question from someone who is aware of Skype, and dabbled with it, but never adopted it for regular use: Why is this such an issue?
It doesn't just seem to me, but it's been confirmed here, that there are many alternatives to Skype many of which are accessible. It will also be interesting to see what UI interface changes occur, particularly with regard to accessibility, with Skype 8.0.
